The said gas conducting pipe i's Puriliers, of which the following is a speciticlation. i

This invention is an improved gas sterilizer and purifier particularly adapted for use in connection with Catacombs. vaults or the like for purifying and sterilizing the gases vented from the hermetically `sealed compartments in which the bodies of the dead are placed and the said invention consists inthe construction, combination and arrangement of devices hereinafter described and claimed.

'The accompanying drawing is partly a sectional view and partly an elevation of a gas purifying and sterilizing apparatus constructed in accordance with this invention.

In the embodiment of the invention here shown. a plpe 1 is provided for attachment l to and communication with the vault or i' the like structureA indicated at a to afford a vent for the gases and the said pipe is preferably provided with a suitable pressure gage-2 and a cut-off valve 3. To the saidI pipe 1s, connected one end of a, gas purifying and sterilizing duct 4 which within the scope of the invention may be of any suitable eonstructlon and is provided with a pair as U-shaped. The arm 7 ofthe trap 5,is connected to the gas venting pipe 1 by the elbow 8 and reducer cap 9.- The arm 10 of saidV trap 5 vis connected by an elbow 11 to the arm 12 of the trap-'6 and the arm 13 of said trap 6 is connected toa gas discharge pipe 11 by an elbow 15 and a reducer cap 16, said discharge pipe being preferably provided with a/.valve 17 whereby it may be opened or closed. The parts ofthe said 'duct are here vshown as ^detachable and The said duct with its ^traps may be constructed of any suitable screwed together.

material and itswpartsA may be secured togetherby any sultable means. I do not desire to limit myselflinI these particulars.

` The ytrap 5 is, in use, nearly filled with a suitable liquid germicide, and preferably one l of the arms of the germicide tra-p is provided with a gage 18 whereby the quantity of germicide therein may benoted. gas

wl lich is preferably of disposed` in the germicide trap, extends downward through the arm 7 thereof, through the lower portion of the said trap and its discharge end is provided with a irose 21, which rose presents a perforated diaphragm of larger diameter than the said gas conducting pipe 19 and is disposed in the lower portion of the arm 10 of the 2 germicide trap where it is submerged in the column of liquid'germicide in said arm of the trap.'y so that the gases which pass :through the said gas conduct-ing pipe 19 :escape upwardly from the upturned disg charge end of said pipe are didused by the l rose and are caused to bubble up through z the column of liquid germicide in the arm of the germicide trap and hence 'such gases are thoroughly sterilized -by such germicide. gas pressure in the gas conducting pipe 19 prevents the liquid germicide from entering i the said pipe; y

Near the lower portion of the arm 12 or intake arm of the purifying trap 6 is v a foraminous ,diaphragml 22 which is here f shown as supportedon an annular shoulder Il2 in'said arm. The said foraminous diaphragm supports a quantity 4of dry pulveri :ized charcoal or other suitable as purifyi ing material, indicated at 2l. p rewed in the lower end of the arm 13 of the purifying trap is aconical perforated bottom piece 25 which supports a quantity of cotton or other suitable fibers or other particle arresting or absorbent 4material 26. A retainin foraminous cover 27'in the upper ,portion o said arm 13-and here shown as bearing on an annular shoulder 28 in the s'aid arm 13, is

also provided. v

The'gases which result from decomposition are caused, either by their own expanl sive force orby the action of a suitable puiiip I bodies lie and the 'pipe 19 through and are A to pass from the compartments in which the i sterilized in and by the body of liquid ermieide in the germicide trapv as herein efore described. They then -pass downwardly l through the body of pulverized charcoal I' or other purifying agent in the arm 12 of i thevpuriying trap and from said arm passv It will be` understoodl that the upwardly through the body of particle 'arresting and absorbent material 26 through the arm 13 of said puriyingtrap, and finally throughthepipe 14 into the outer air. 5 Hence the'wsaid gases are sterilized, purified and 'rendered entirely innocuous.

Whatisv claimed is 1. The herein described gas purifier and sterilizer comprising a duct formed of a plurality ofconnected U-sha ed traps, one of said traps formin a cham er for the reception of the liqui. gerniicide nand the other havino the arms thereof provided with` foraminous `diaphragms and respectively containing the gas purifying material and an absorbentfmaterial', a vent' pipe connected to ythe intake arm of theliquid'germicide trap and a gas conducting pipe connected to said vent pipey and locatedin said liquid germicide trap and discharging therein at E shaped trap a lower point to cause gasto ascend from said discharge through vthe germicide in said tra 2E.) In apparatus of theclass described, a vent pipe, a reducer cap thereon, a U- duct'of greater diameter than the vent pipe and'vhaving one of itsjarrns connected at the upper end. to the reducer cap, and a gas conducting' pipe, of less diameter than and located in saidtrap, said pipe being connected to the vent pipe ata distance within the`reducer cap and having a discharge located4 in the lower portion of the tra-p duct. p

In testimony whereof I aixiny signature in presence of two witnesses.
